- In process_multipart_form_data, replace post_data = content_data with post_data = strdup(content_data) when there are no non-file fields.
- content_data is freed by caller (ccsp_post_module_open), so aliasing caused double-free/heap corruption.
- Prevents crash pattern seen as SIGSEGV/SIGABRT in core dumps.

Pull request overview
Fixes a double-free/heap corruption in the multipart POST parsing fallback path by ensuring post_data does not alias content_data (which is freed by ccsp_post_module_open after parsing).
Changes:
- In
process_multipart_form_data, replacepost_data = content_datawithpost_data = strdup(content_data)when there are no non-file fields. - Add an allocation failure log for the
strdupcall and document the ownership rationale inline.
